Active clinical trials for "Pulmonary Disease, Chronic Obstructive"

To investigate the relation the nreural drive and intrinsic positive end-expiratory pressure(PEEPi) of the chronic obstructive pulmonary disease(COPD) patients with respiratory failure.In present study the PEEPi of COPD patients was increased by increasing the resistance of the respiratory system, the change of the neural drive was recorded.

There are few studies about immunological explorations in COPD. Because of the complications of lung biopsies, analyses are generally made on blood samples instead of lung tissue. No study tried to classify COPD vs Asthma vs ACOS. The investigators wondered if there were differences in biomarkers between these groups. The investigators decided to open a pilot-study among COPD patients followed in Amiens-University Hospital. Each patient will be examined and a blood-test will be performed.

The real world study aims to assess effectiveness and safety profile between tiotropium/olodaterol (Tio/Olo) and inhaled corticosteroids(ICS) / Long-acting β2-agonists (LABA) in patients with chronic obstructive pulmonary disease (COPD) in Taiwan. The data used in this study will come from the Taiwan National Health Insurance (NHI) claims data between 2014 and 2019.

This study is primarily aimed to investigate whether PROs can be improved after the initiation of BGF pMDI in real world clinical settings. While the study is 12-weeks in duration, the initial 4-week period will be used to assess immediate onset of benefits while the full study length will serve to demonstrate durability in response. Study design: This is a 12-week, multi-center, prospective observational study in which a total number of 107 patients will be enrolled. Adult outpatients with COPD without asthma history and who initiate on BGF pMDI as decided by the physicians in their routine clinical care will be consecutively invited for this study. Investigators (physicians) make screening their patients prior to the study entry and make informed consent explanation at their usual visit timing to the all eligible patients. After fulfilling eligibility criteria at study entry, the patients are enrolled in the study and the investigators will follow up the patients as in routine clinical practice and collect the data at baseline, at week 4 and week 12. Data Source(s): The study sites will be selected where BGF pMDI is used as a treatment option for COPD patients. Investigators participating in the study evaluate lung function (i.e., spirometry) for COPD patients in a daily practice Statistical Analysis: All data including patient characteristics at baseline will be summarized using appropriate descriptive statistics. Where applicable, changes from baseline at each timepoint will also be summarized using descriptive statistics. A comprehensive statistical analysis plan (SAP) including more details will be prepared prior to the database lock.

The main objective of this trial is to prove that MRI - as the imaging modality without the use of ionizing radiation - can replace CT for structural and functional regional phenotyping of COPD. The identification of different COPD phenotypes, such as the "emphysema-type" and the "airway-type", is important because therapy and prognosis will be different. The medical problem addressed in this trial is the image-based phenotyping of COPD. The sensitivity and specificity of MRI will be compared to Lowdose-CT serving as the gold standard. MRI and CT of the lung will be performed in a multi-centre cohort of 625 COPD-patients from the main COSYCONET cohort. The reliability of the MRI results will be demonstrated. MRI phenotypes will be evaluated visually and using software with quantitative read-outs. The agreement of both will be determined. The additional information of MRI over CT will be assessed.

This is an exploratory study to further develop an imaging platform for the assessment of whole lung neutrophil retention. The primary objective of the study is to quantify and compare neutrophil retention in the lungs of lipopolysaccharide-challenged healthy subjects, saline-challenged healthy subjects and subjects with stable COPD. There will be two treatment groups, one with healthy subjects and the other with subjects with stable COPD. The total duration of this study for healthy subjects will be approximately 1 week, in addition to the screening window of 28 days. The total duration of this study for subjects with COPD will be approximately 1 week for those that complete Visit 1 only, and approximately 2 weeks for those subjects with COPD that return to the unit for Visit 2 7-10 days later, in addition to the screening window of 28 days.

Real-world data on the effects of a fixed-dose combination Long-acting beta agonists + long-acting antimuscarinic agent (LABA+LAMA) therapy with tiotropium and olodaterol administered in a single device, in COPD patients who need treatment with two long-acting bronchodilators, is not available. This is a self-controlled study design enrolling consented COPD patients who will be treated with Spiolto Respimat according to the approved Summary of Product Characteristics (SmPC).

The study is an observational multicenter descriptive study. It is planned to enroll approximately 1250 subjects with severe and very severe COPD hospitalized for the reason of COPD exacerbation into departments of pulmonology or therapy. The study will be conducted in approximately 20-25 institutions of treatment and prevention in Russian Federation and will include about 50 to 60 subject at each clinical site.

A real world study to determine the effectiveness of a patient support service to aid COPD patients in their self management.

Pulmonary rehabilitation clearly increases exercise capacity, but its effect on physical activity in the home and community settings is less clear. It may take a longer time for this increase in physical activity to occur. It has been stated in an editorial that it takes 3 months to train the muscles but 6 months to train the brain. The Investigators will first evaluate the change in physical activity following pulmonary rehabilitation using state-of-the-science motion detectors, then Investigators will follow the trajectory of physical activity over the next several months.
